Just bagged this Omega Electronic f300Hz Chronometer from 1972 with the original signed bracelet.
The movement is Omega's "upgrade" of the licensed Bulova/Accutron tuning fork movement. The
name, of course, refers to the tuning fork's vibration frequency of 300 times per second.
Can't wait to get my hands on it...my 1968 Accutron "Railroad" needs a partner!
